In this best-selling, heartwarming tale, a lonely older man takes home a pet-shop kitten that no one else wants. It doesn't take long for the pair to warm up to each other, and soon, they're inseparable. Told through the eyes of both the man and his cat, this sweet and hilarious story is a balm for the soul!

Though he still can't perform on stage, Kanda challenges himself with street piano. He never imagined his audience would include his former teacher, Margarethe Dressel. The ever-present Fukumaru is ready to win new hearts--luckily, Kanda's mentor is a fellow cat lover! Then, Geoffroy becomes Kuju's piano teacher, but the lesson gets off to a rocky start.
